Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523342, here are decompositions:

13 + 31523329 = 31523342
181 + 31523161 = 31523342
199 + 31523143 = 31523342
211 + 31523131 = 31523342
223 + 31523119 = 31523342
229 + 31523113 = 31523342
673 + 31522669 = 31523342
709 + 31522633 = 31523342

Showing the first eight; more decompositions exist.
